' DlE FOR MAKING HOLLOW SHEET-METAL WINDOW OR OTHER SASHES.

SPECIFICATION forming part of Letters Patent No. 747,666, dated December22, 1903.

Application filed November 12,1902. serial No. 131.044. (N o modeLl Toall whom it may concern:

Be it known that we, FRANK VOIGTMANN, of Chicago, Illinois, and SILAS H.POMEROY, of New York, State of New York, both citizens of the UnitedStates, have jointly invented certain new and usefullmprovements in Diesfor Making Hollow Sheet-Metal Window or other Sashes, of which thefollowing is a specification.

Our invention relates to the manufacture of hollow sheet-metalwindow-sashes, such as are commonly employed in fireproof and otherbuildings, and has for its primary object to provide meanswhereby ahollow sheetmetal sash may be produced with. a minimum number of partsand without seams or joints at the corners.

Another important object of the invention is to cheapeu the cost ofproduction of such articles. j

lhese objects we attain through the use of novel and improved means fortheir manufacture in the nature of a die which is capable of stampingfrom rectangular sheet-metal blanks the inner and outer face members ofthe sash in integral forms, respectively, and requiring only to besuitably connected or united at theirinner and outer meeting edges.

A die embodying the principle of our invention in the best form we haveas yet devised is illustrated in the accompanying drawings, wherein-Figure l is a plan view of the top or'movable member of the the. Fig. 2is a similar plan view of the bottom or stationary member of the die.Fig. 3 is an enlarged crosssectional detail view through the mating im-vpression members of the die and their bedblocks, showing said members inregistration with a sheet-metal blank stamped to its in- Fig. at is afragmen'tary detail view, in vertical section, through. one of thebed-blocks, illustrating the means for securingand adjusting theimpression members on their supporting-blocks. Fig. 5 is a sideelevation of the upper movable 01' stamping member of the die. Fig. 6

In carrying out our invention we provide a pair of preferablyrectangular bed-blocks l0 and 11, constituting the supporting andcarrying elements of the top and bottom mem- The bed-block 10 isprovided on its under surface with a series of longiv tudinally andtransversely disposed undercut grooves or channels 10, and the bedblock11 is similarly'provided on its upper surface with a correspondingseries of longitudinally and transversely extending undercut grooves 11.The upper bed-block 10 may be mounted on the lower end of any suitableactuating means, such as the stem 12. (Shown in Fig. 5.)

"lheimpression-forming elements of the die members proper are cut frommetal bars of uniform cross-sectional dimensions and contour,being'preferablymade from commer-.

cially-rolled steel bars having inter-fitting or mating faces betweenwhich the sheet-metal blanks are compressed and shaped. The bar whichserves as the lower passive member of the die is cut into four sectionswith miter-ed joints, the two longer sections (indicated by 13) servingto the two shorter sections '(indicated by 14) serving to form therails. These elements are arranged to. constitute a rectangular frame,as shown in Fig. 2, and are rigidly secured upon their supportingbed-block 11, with capacity for relative adjustment to secure a perthefollowing devices: 15 designates margin-hooks dovetailed in the grooves11 beneath and engaging the under surfaces of the stile-formers 13 andthe rail-formers 14:. In order that these margin-hooks may grip theirrespective rail and stile formers and secure the latter rigidly to thebed-block, the outer projecting ends 'of the margin-hooks are overlaidtransversely by clamp-bars 16, which are each provided with an inclinedo" beveled inner edge, as shown at 16 in Fig. 3, registering with aninversely-inclined outeredge 13 on the outer form the stiles of the sashand margin of the stile or rail former engaged thereby. At the pointswhere the clampbars overlie the rearward extensions ofthe marginhooksthe former are provided with throughslots 16*, Fig. 3, slightlyelongated in a direction transversely of the bars, through which slotsare passed screw-bolts 17, the lower threaded ends of which engagethreaded holes in the underlying extensions of the marginhooks. Thisconstruction enables the stile and rail formers to be adjusted into asnug and perfect fit at their mitered corners and to be rigidly securedin such positions by simply turning up hard the screw-bolts 17 after theclamp-bars 16 have been forced inwardly to crowd the stile andrailformers hard against each other at the corners and against the innerabutments of their respective marginhooks, the turning up of thescrew-bolts tending to draw the oblique sides of the marginhooks intoclose frictional engagement with the undercut side walls of theirrespective grooves, whereby said margin-hooks are securely held againstany sliding movement longitudinally of their grooves.-

The upper active member of the die is constructed and assembled inprecisely the manner already described in connection with the lower orpassive member, with the exception that the elements thereofconstituting the immediate impression members are of course cut from asingle length of bar that is rolled or otherwise formed with a surfaceof such a contour or pattern as will exactly register with and interfitthe opposed meeting face of thecompanion bar from which the rail andstile formers already described were cut.' In Fig. 1 the stile'stampsare indicated at 18, the rail-stamps at 19, the margin-hooks holding thesame at 20, the clamp-bars for the rail and stile stamps at 21, andtheir adjusting screw-bolts at 22. i

It is desirable to provide in connection with the lower stationarymember of the die means whereby the blank may be accurately positionedthereon prior to the stamping operation, and such means may convenientlyconsist of a series of vertical pins 23, grouped around the two ends andone side of the framed structure constituting the lower stationaryelement of the die, said pins extend ing, as shown in Fig. 3, to aheight slightly above the top surface of the die member and adapted whenthe members of the die are in operative engagement upon a blank to entercorrespondingly-positioned holes 24, formed in the outer marginal p01'ion of the upper movable member of the die. Said pins and holes are ofcourse so relatively positioned as to register only when the cooperatingfaces of the die members are also in perfect registration. v

\Ve will now describe the manner in which the die is operated and thecompleted sash formed from the resulting product of the die. Fig. 7shows in plan View the integral flat rectangular sheetmetal blank(designated byA) constituting the article subjected to the operation ofthe die. The upper member of the die being raised to a sufiicient heightabove the lower stationary member, this rectangular blank is readilyinserted in position upon the face of the lower die member with its twoend and rear sides contacting the several pins 23, which insures itsaccurate positioning. Thereupon the upper stamping member of the die isdepressed and impinging upon the top of the blank bends and forces thematerial thereof down upon the stationary impression member, compressingsaid material between the opposed and mating faces of the impressionmembers, and thus obviously imparting to the blank the crosssectionalform of said mating faces, as clearly shown in Fig. 3. The upper diemember is then raised, the bent and crimped sash member removed, andanother blank inserted and subjected to the same operation. Upon theremoval of the second blank the two bent and crimped frames may then bereadily assembled intoa complete sash in the manner illustrated in Figs.8 and 9. To do this, the two stamped members, which are designated by A,are placed in opposed relation, as shown in Fig. 8, and the inner andouter marginal portions of the members are turned inwardly, as shown ataand a, respectively, the extreme inner edges of the inwardly. bentmarginal portions Ct being again bent inwardlyat right angles towardeach other. as shown at 61*. The companion members A thus assembled andshaped are connected and united into the form of a complete sash througha fiat con uection-strip B, having outwardly-bent marginal portions b,which are pressed into interlocking engagement with the edges a, whilethe inwardly-bent margins a and their meeting extensions a togetherconstitute a housing for the edge portion of the glass 0 of the sash.

From the foregoing it will be seen that by ourinvention We provide a diewhich is capa ble of forming up from rectangular integralsheetmetal'blanks the face members of a hollow metal sash, said sashbeing without transverse seam or joint at its corners, and thuspossessed of great strength and rigidity.

It will also be observed that our invention dispenses with the necessityof all special moldings or castings to form the impression elements ofthe die, since these elements are each constructed entirely from asinglelength of rolled bar-steel or other metal cut and mitered into sectionscorresponding with the marginal members of the sash to be formedthereby. While we have shown and described a die adapted to the prodnotion of a simple rectangular sash, yet itwill be obvious that withinour invention dies mightbe made of any other form in outline. It is alsoobvious that the die members may within our invention be formed withcoacting faces of any desired or convenient outline or contour.

An important advantageresulting-from the IIO . tive channels.

' plates or blocks resides in member comprising an impression m'edescribed mannerof mounting the impressionmembers on their respectivesupporting the fact that the latter are capable of receiving andcarrying impression members of widely varying sizes, for which purposesaid impression members maybe readily removed and others substituted bysimply withdrawing "the marginal clamping-bars and read usting themarginhooks inwardly or outwardly of their respect While we havedescribed the die as con.- sisting of a stationary lower member and anupper movablemember, it is perfectly obvious that, if desired, the uppermember might be made stationary and the lower member movable, or bothmove toward and from each other. 'Hence Within the purview of 'ourinvention any desired or convenient relative movement may be imparted tothe die members.

We claim- 1. Ina die of the character described, a die member comprisingan impressionmember composed of a plurality of" sections cnt'from arolled-metal bar and connected up end to end'toform aclosed frame, abed-block, and independent devicesfor adjustably securing the respectivesections of said'Trame-shaped i pression member to said bed-block.

. In a die of the character described, a die composed of a plurality ofstraight sections cut from a rolledmetal bar and connected up withmitered endwise-abutting joints to form a'closedframe, a bed-block, andindependent clamping devices for adj ustably securing the .respectivesections'of said frameshaped'impression member to the surfaceof c saidbed -block.

3. In a die of the character described, adie members might be made tothe frameshaped impression hooks in said channels and thereby securingsaid frame-sections in closely-fitting relation to each other. p

4. The herein-described adjustable die for 55 forming hollow sheet-metalwindow-sashes, consisting of a pair of cooperating die members, eachmember comprising an impression member composed of a plurality ofstraight sections cut from a metal cross-sectional dimensions andcontour, and connected up with mitered endwise-abutting joints to form aclosed frame, a bed-block having its surface provided with channelsextending radially thereof, and in directions 65 at right angles to therespective sections of member, inde-- pendent'margin-hooks in thechannels of said bed -block embracing said frame-sections, and meanssecuring said frame-sections in 0 the grasp of the margin-hooks and thelatter fixed against movement in their respective channels.
